Light source module device and fluid sterilizing device

Abstract

To provide a light source module device capable of controlling the light distribution of ultraviolet light with a small and simple structure. A light source module device 7 includes a substrate 4, a light source 3 mounted on the substrate 4 and emitting ultraviolet light, a reflector 8 mounted on the substrate 4 so as to surround the light source 3 and reflecting the ultraviolet light by its inner surface to guide the ultraviolet light toward an irradiation target, and a cap-like optical member 9 mounted so as to cover the outer circumference of the reflector 8 and condensing or diffusing the ultraviolet light.

What is claimed is: 
     
       1. A fluid sterilizing device comprising:
 a light source module device; and 
 an enclosure including a channel where fluid to be sterilized flows in an axial direction, at least one inlet through which the fluid to be sterilized flows in, and at least one outlet through which the fluid to be sterilized flows out, wherein 
 the light source module device includes:
 a substrate; 
 a light emitting device mounted on the substrate configured to emit ultraviolet light; 
 a reflector disposed on the substrate so as to surround the light emitting element, and configured to reflect the ultraviolet light on an inner surface thereof to guide the ultraviolet light toward an irradiation target; 
 an optical device having a cap-like shape and mounted so as to cover an outer circumference of the reflector for transmitting, condensing, or diffusing the ultraviolet light; and 
 a frame disposed so as to surround an outer circumference of the cap-like shaped optical device, wherein 
 
 the at least one inlet is formed on one end portion of the enclosure in the axial direction, 
 the light source module device is attached to an end portion of the enclosure via a sealing structure, the end portion being opposite side of the at least one inlet, 
 a triangular groove is formed by the frame, the outer circumference of the cap-like shaped optical device, and the end portion of the enclosure at the opposite side of the at least one inlet, and 
 the sealing structure is disposed in the triangular groove, and seals between the cap-like shaped optical device and the end portion of the enclosure at the opposite side of the at least one inlet. 
 
     
     
       2. The fluid sterilizing device according to  claim 1 , wherein a portion of the optical device through which the ultraviolet light passes is formed convex, concave, or planar relative to an open end surface of the reflector. 
     
     
       3. A fluid sterilizing device comprising:
 the light source module device according to  claim 1 ; and 
 an enclosure including a channel where fluid to be sterilized flows in an axial direction, at least one inlet through which the fluid to be sterilized flows in, and at least one outlet through which the fluid to be sterilized flows out, 
 wherein 
 the at least one inlet and the at least one outlet are formed on an outer circumference of the enclosure, and 
 a second light source module device according to  claim 1 , wherein 
 the light source module device is attached to an end portion of the enclosure in the axial direction via a sealing structure as recited in  claim 1 , 
 the second light source module device is attached to another end portion of the enclosure in the axial direction via another sealing structure, 
 each of the two light source module devices includes a triangular grove formed by the frame, the outer circumference of the cap-like shaped optical device, and the respective end portion of the enclosure, and 
 each sealing structure is disposed in the respective triangular grooves, and seals between the cap-like shaped optical device and the respective end portion of the enclosure. 
 
     
     
       4. A fluid sterilizing device comprising:
 a light source module device; and 
 an enclosure including a channel where fluid to be sterilized flows in an axial direction, at least one inlet through which the fluid to be sterilized flows in, and at least one outlet through which the fluid to be sterilized flows out, 
 the light source module device includes:
 a substrate; 
 a light emitting device mounted on the substrate configured to emit ultraviolet light; 
 a reflector disposed on the substrate so as to surround the light emitting device, and which reflects the ultraviolet light on an inner surface thereof to guide the ultraviolet light toward an irradiation target; and 
 an optical lens attached to an open end portion of the reflector to seal the reflector for condensing or diffusing the ultraviolet light, and 
 a frame disposed so as to surround an outer circumference of the reflector 
 
 wherein 
 the at least one inlet is formed on one end portion of the enclosure in the axial direction, 
 the light source module device is attached to an end portion of the enclosure via a sealing structure, the end portion being opposite side of the at least one inlet, 
 a triangular groove is formed by the frame, the outer circumference of the reflector, and the end portion of the enclosure at the opposite side of the at least one inlet, and 
 the sealing structure is disposed in the triangular groove, and seals between the reflector and the end portion of the enclosure at the opposite side of the at least one inlet.
